Q: Does this tool can only convert Option File?
A: Absolutely not! We will try to keep developing the app to support more and more files, and make it even better than ever. One thing for sure, Option File, Database, Kits, Face, and Stadium are the files that are already on our list!

Q: I tried to convert my Option Files, but it says "0 file has been converted" !
A: Make sure that you decrypt your Option Files using PES 2017 File Crypter Tool by Devil Cold52 if you are on PC, or make sure that you extract the internal part of your Option Files using Le Fuffle or Horizon if you are on XBOX.
